Sure, in some ways that's more a quirk of language, rather than spectrum, but I dunno. When you make red darker it looks blacker. When you make pink look darker, it looks ... bluer.
I was, of course, mocked for this and generally kept down by The Man. And as I'm neither a lighting designer nor a painter,* I don't have the background to make a better argument, so I let it drop.
Thanks to Alice, Facebook, and NPR, this little tidbit has fallen into my lap.
I'm probably still wrong, but somehow I feel --- less wrong.
There is no blue food. There is no pink light.
*Because colors in light and colors in pigment are two separate things. The former is additive color and the later is subtractive color.**
**A fact I'll be able to retain until just after I post this, of course.
